2008-07-11ftrace: separate out the function enabled variableSteven Rostedt
Currently the function tracer uses the global tracer_enabled variable that is used to keep track if the tracer is enabled or not. The function tracing startup needs to be separated out, otherwise the internal happenings of the tracer startup is also recorded. This patch creates a ftrace_function_enabled variable to all the starting of the function traces to happen after everything has been started.

2008-07-11ftrace: add ftrace_kill_atomicSteven Rostedt
It has been suggested that I add a way to disable the function tracer on an oops. This code adds a ftrace_kill_atomic. It is not meant to be used in normal situations. It will disable the ftrace tracer, but will not perform the nice shutdown that requires scheduling.

2008-07-11ftrace: use current CPU for function startupSteven Rostedt
This is more of a clean up. Currently the function tracer initializes the tracer with which ever CPU was last used for tracing. This value isn't realy useful for function tracing, but at least it should be something other than a random number.

2008-07-11ftrace: move sched_switch enable after markersSteven Rostedt
We have two markers now that are enabled on sched_switch. One that records the context switching and the other that records task wake ups. Currently we enable the tracing first and then set the markers. This causes some confusing traces: # tracer: sched_switch # # TASK-PID CPU# TIMESTAMP FUNCTION # | | | | | trace-cmd-3973 [00] 115.834817: 3973:120:R + 3: 0:S trace-cmd-3973 [01] 115.834910: 3973:120:R + 6: 0:S trace-cmd-3973 [02] 115.834910: 3973:120:R + 9: 0:S trace-cmd-3973 [03] 115.834910: 3973:120:R + 12: 0:S trace-cmd-3973 [02] 115.834910: 3973:120:R + 9: 0:S <idle>-0 [02] 115.834910: 0:140:R ==> 3973:120:R Here we see that trace-cmd with PID 3973 wakes up task 9 but the next line shows the idle task doing a context switch to task 3973. Enabling the tracing to _after_ the markers are set creates a much saner output: # tracer: sched_switch # # TASK-PID CPU# TIMESTAMP FUNCTION # | | | | | <idle>-0 [02] 7922.634225: 0:140:R ==> 4790:120:R trace-cmd-4789 [03] 7922.634225: 0:140:R + 4790:120:R Signed-off-by: Steven Rostedt <srostedt@redhat.com> Cc: Steven Rostedt <srostedt@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-07-08NFS: Fix readdir cache invalidationTrond Myklebust
invalidate_inode_pages2_range() takes page offset arguments, not byte ranges. Another thought is that individual pages might perhaps get evicted by VM pressure, in which case we might perhaps want to re-read not only the evicted page, but all subsequent pages too (in case the server returns more/less data per page so that the alignment of the next entry changes). We should therefore remove the condition that we only do this on page->index==0. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2008-07-08palm_bk3710: fix IDECLK period calculationSergei Shtylyov
The driver uses completely bogus rounding formula for calculating period from the IDECLK frequency which gives one-off period values (e.g. 11 ns with 100 MHz IDECLK) which in turn can lead to overclocked IDE transfer timings. Actually, rounding is just wrong in this case, so use a mere division for a safe result. While at it, also: - give 'ide_palm_clk' variable a more suitable name; - get rid of the useless 'ideclkp' variable; - drop the LISP stype 'p' postfix from the 'clkp' variable's name. :-) Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Cc: mcherkashin@ru.mvista.com Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

This fixes post-2.6.25 regression since ide_default_irq() define could shadow ide_default_irq() inline. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-07-08Correct hash flushing from huge_ptep_set_wrprotect()David Gibson
As Andy Whitcroft recently pointed out, the current powerpc version of huge_ptep_set_wrprotect() has a bug. It just calls ptep_set_wrprotect() which in turn calls pte_update() then hpte_need_flush() with the 'huge' argument set to 0. This will cause hpte_need_flush() to flush the wrong hash entries (of any). Andy's fix for this is already in the powerpc tree as commit 016b33c4958681c24056abed8ec95844a0da80a3. I have confirmed this is a real bug, not masked by some other synchronization, with a new testcase for libhugetlbfs. A process write a (MAP_PRIVATE) hugepage mapping, fork(), then alter the mapping and have the child incorrectly see the second write. Therefore, this should be fixed for 2.6.26, and for the stable tree. Here is a suitable patch for 2.6.26, which I think will also be suitable for the stable tree (neither of the headers in question has been changed much recently). It is cut down slighlty from Andy's original version, in that it does not include a 32-bit version of huge_ptep_set_wrprotect(). Currently, hugepages are not supported on any 32-bit powerpc platform. When they are, a suitable 32-bit version can be added - the only 32-bit hardware which supports hugepages does not use the conventional hashtable MMU and so will have different needs anyway.

2008-07-06vsprintf: add support for '%pS' and '%pF' pointer formatsLinus Torvalds
They print out a pointer in symbolic format, if possible (ie using symbolic KALLSYMS information). The '%pS' format is for regular direct pointers (which can point to data or code and that you find on the stack during backtraces etc), while '%pF' is for C function pointer types. On most architectures, the two mean exactly the same thing, but some architectures use an indirect pointer for C function pointers, where the function pointer points to a function descriptor (which in turn contains the actual pointer to the code). The '%pF' code automatically does the appropriate function descriptor dereference on such architectures. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-07-06vsprintf: add infrastructure support for extended '%p' specifiersLinus Torvalds
This expands the kernel '%p' handling with an arbitrary alphanumberic specifier extension string immediately following the '%p'. Right now it's just being ignored, but the next commit will start adding some specific pointer type extensions. NOTE! The reason the extension is appended to the '%p' is to allow minimal gcc type checking: gcc will still see the '%p' and will check that the argument passed in is indeed a pointer, and yet will not complain about the extended information that gcc doesn't understand about (on the other hand, it also won't actually check that the pointer type and the extension are compatible). Alphanumeric characters were chosen because there is no sane existing use for a string format with a hex pointer representation immediately followed by alphanumerics (which is what such a format string would have traditionally resulted in).
